Effective Data Transmission and Control Based on Social Communication in Social Opportunistic Complex Networks

open access: yesComplexity, 2020
In opportunistic complex networks, information transmission between nodes is inevitable through broadcast. The purpose of broadcasting is to distribute data from source nodes to all nodes in the network.

Successive interference cancellation in multistream faster-than-Nyquist Signaling [PDF]

open access: yesProceedings of the 2006 international conference on Wireless communications and mobile computing, 2006
In earlier work we have extended Mazo's concept of faster than-Nyquist signaling to pulse trains that modulate adjacent subcarriers, a method we called two dimensional Mazo signaling. The signal processing is similar to orthogonal frequency division multiplex (OFDM) transmission.

Finite Length Analysis of Irregular Repetition Slotted ALOHA in the Waterfall Region [PDF]

open access: yes, 2018
A finite length analysis is introduced for irregular repetition slotted ALOHA (IRSA) that enables to accurately estimate its performance in the moderate-to-high packet loss probability regime, i.e., in the so-called waterfall region.

Power control for successive interference cancellation algorithm based on game theory

open access: yesTongxin xuebao, 2015
It was proved that implementation of successive interference cancellation could improve network throughput in wireless networks,while in order to maximize network throughput,it was a NP-Hard problem that how to control transmission power when successive ...

Mixed numerologies interference analysis and inter-numerology interference cancellation for windowed OFDM systems [PDF]

open access: yes, 2018
Extremely diverse service requirements are one of the critical challenges for the upcoming fifth-generation (5G) radio access technologies. As a solution, mixed numerologies transmission is proposed as a new radio air interface by assigning different ...

Joint-Detection and Interference Cancellation Based Burst-by-Burst Adaptive CDMA Schemes

open access: yes, 2002
Spread adaptive quadrature amplitude modulated (AQAM) code-division multiple access (CDMA) is proposed as a powerful means of exploiting the time-variant channel capacity fluctuations of wireless channels.

Uplink Non-Orthogonal Multiple Access (NOMA) Decoding Based on Successive Parzen Windows Interference Cancellation

open access: yesIEEE Open Journal of Vehicular Technology
In this paper, a novel decoding kernel method based on Successive Parzen Windows Interference Cancellation (SPWIC) is proposed for the Non-Orthogonal Multiple Access (NOMA) uplink. The procedure leverages on the diversity in both angle and received power

Successive Integer-Forcing and its Sum-Rate Optimality

open access: yes, 2013
Integer-forcing receivers generalize traditional linear receivers for the multiple-input multiple-output channel by decoding integer-linear combinations of the transmitted streams, rather then the streams themselves.
